INVENTOR N'NESSES ATTORNEY WILLIAM C. NELSON, F ROCHESTER, NEW HAMPSHIREi CARTRIDGE-SHELL Specification of Letters Patent.

Patented J an. 21., 1919.

Application led January 17, 1916. Serial No. 72,592.

To all whom it may concern: l

Be it known that I, WILLIAM C. NELSON, a subject of King of Sweden,residing at Rochester, in the county of Stratford and State of--NewHampshire, have invented certain new anduseful Improvements inCartridge-Shells, of which the following is a specification.

This invention relates to cartridge shells and has forits primary objectto provide a xtridge shell whose body is composed of Another object ofthe invention is to provide a cartridge shell, the body of which issecured to the head, between the slit edges thereof.

A further object of this invention is to -I provide a cartridge shellwhich will have the strength of one composed entirely of metal, butlwhich will be materially ,lighter 'iin weight and therefore much moreconvenient to transport.

Still yanother object of this invention is to provide a cartridge shellwhich will not be a conductor of electricity, making the same much moresafe.

With these and other objects in view, this invention consists in thenovel construction, combination and arrangement of parts as will behereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part ofthis specilication, in lwhich similar reference characters indicatecorresponding parts. and in which,

Figure 1 is a fragmentary sectional view of a cartridge shell withthehead detached.

Fig. 2 is a similar view with the head attached, and Fig. 3 is alongitudinal sectional view of a small sized cartridge shell.

Although but one size of cartridge shell is hereinafter described, it isunderstood that this invention may be used in connection with fire armsof diiferent calibers, such as rifles, shot guns, iield guns, machineand naval guns. Also the cartridge shell may be made in different tapersand shapes such as bottle neck and the like.

Referring to the drawings, 5 indicates the body of the cartridge shellwhich is composed of hard fiber, which is commonly known as vulcanizedfiber, bone or hard fiber. @ne end of the body is slightly reduced,forming a shoulder 6, and the reduced end is provided with a pluralityof circumferential grooves or recesses 7, the inner walls of which formribs 8 on the interior of the body, the

purpose of which will be more fully de' is slit to form the two sections11 and 12,

hereinafter termed the outer and inner Walls respectively. The outerwall has on its inner periphery, a plurality of circumferential ribs 13,which are received in the recesses 7 in the body, while the innerperiphery of the inner wall is provided with a series of circumferentialgrooves 14. which receive the ribs 8. An annular slit is formed withinthe base portion of the cap 9 and provides means whereby the section 11may be rea-dily bent outwardly.

In assembling the cartridge shell, the head is positioned on the body sothat the ribs 8 are received in the recesses 14C. In order to make atight joint therebetween, the inner wall 12 is pressed against the body.Then the outer wall 11 is forced into engagement with the reduced end ofthe body and the ribs 13 seated in the recesses 7. In this position theedge of the wall 11 rests against the shoulder G and thereby assists inlimiting the movement of the head on the body.

Various changes in the form, proportion and arrangement of parts may beresorted to without departing from the principle or sacrificing any ofthe advantages of this invention as claimed.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

A cartridge shell comprising a cylindrical body having annular exteriorrecessesforming interior ribs, and a shoulder, a cap having a split,said cap including an inner and outer ange forming a recess for thecylindrical body said recess terminating at the split, the flangeshaving recessesand ribs respectively for engaging the recesses 'and ribsof the cylindrical body.

In testimony whereof I affix my signature in presence of two witnesses.
